APPARATUS FOR BOFiING ARTESIAN WELLS.

SPECIFICATION forming part of Letters Patent No. 492,536, dated February28, 1893.

Application filed April 6. 1892. Serial No. 428,099. (No model.)

To all whom it may concern.-

Be it known that I, FRANK O. BROWN, a citiof the United States, residingat Dallas, in the county of Dallas and State of Texas, have inventedcertain Improvements in Apparatus for Boring W'ells, of'which thefollowing is a specication.

My invention relates to certain improvements in apparatus for boringwells, and the object of my invention is to provide an apparatus forthis purpose which shall be simple in its operation and readilyadjustable for penetrating substances of various resistances whereby thebreaking of the drill head will, to a great extent, be prevented, all aswill be more particularly described hereinafter.

In order that my improvements may be the better understood I haveillustrated in the accompanying drawings an apparatusembodying myinvention, in `which drawings- Figure 1 is a plan view and Fig. 2 is aside elevation of the apparatus, drawn to a small scale. Fig. 3 is aview similar to Fig. 2 showing the use of the clamps for rotating thetube without the ropes shown in Fig. 2, and Fig. 4. isa detail view.

In the Views, D represents a heavy bed plate provided with an annularraised facing D on its upper side, which facing is grooved and adaptedto receive balls P, as seen in Fig. 2, to reduce friction. The bed plateis set upon the ground over the spot where it is desired to operate andhas a centrally arranged openin g through itfor the passage of the tubeor casing to which the head is secured.

- B is a bevel gear wheel having a groove in its lower sidecorresponding with and fttin g over the balls P in the groove in facingD', as seen in Fig. 2, and h is a bevel pinion mounted in bearings (notshown) at one side of the apparatus and meshing with gear wheel B,whereby said wheel may be rotated, said pinion being driven from anysource of power, as a whin for instance, also not shown.

A is an annular flat table mounted loosely on a shoulder on wheel B, andhaving its edge projecting beyond the edge of said wheel and engagingjaws f on brackets F secured to the bed plate D, one of said jaws oneach bracket lying above and the other below said table whereby saidtable when rotated, moves between the same, as will be understood byinspection of Fig. 2. Said jaws f are provided with perforations and theedges of the table A are likewise correspondingly perforated wherebysaid table may be locked fast to the bed plate by means of pins Z,inserted through said perforations as shown.

On the boss of wheel B is formed a second gear B', projecting above theupper surface of the tableAand on the upper surface of the table A andon diametrically opposite sides thereof, are mounted upright shafts orarbors N, united by a tie bar M at theirtops, on which shafts aremounted toothed gear wheels C, 0,the bosses of which are in the natureof drums C', C.

E, F., are toothed gear wheels suitably mounted on the upper surface ofthe table and adapted to be thrown into and out of engagement withtherespective gears B and C, C, at will for purposes to be hereinafterset forth.

H is a .frame of inverted V-shape, mounted on the table A and bearing atits apexa hook lo, having a screw threaded shank passing through acollar h on said frame and engaging a hand wheel K, thereabove, wherebythe height of said hook above table A may be regulated.

J is a block mounted on said hook and L is a wire rope or chain, passingover the sheave of said block and down on each side of the same, takingunder sheaves I, I, secured on arms projecting upward from table A.Thence said rope L passes, in opposite directions to and around therespective drums C on each side of the table.

O represents the tube or casing to which the drill head is secured andto which it is desired to impart a downward as well as rotary movement,and this tube passes through co-inciding openings formed in wheel B andbed plate D, which openings should be of sufficient size or diameter toadmit of the passage therethrough ofthe couplings employed forconnecting the several pipe sections. j

From the respective drums C', C', the rope L passes, in oppositedirections, about the tube O, as seen in Fig. 2, and back again to thedrum C on the opposite side of said table.

As shown, three strandsfof said rope are em- IOO ' will be understood.

a l agate@ pioyed on each side of the apparatus but the number ofstrands is vunimportant and may be varied according to circumstances,depending on the substance to be operated on, and consequent resistancetending to cause slipping of the rope on said tube O.

The method of operating the apparatus is asfolloWs:-The apparatus havingbeen set in place for operation, the tube O, with the drill head issecured in place and the ropes passed around the same and the drums andpulleys. The slack is then taken upA by means of the hand wheel andscrew on hook 7c after which rotary motion is imparted to the gears rb,B,- and table A, said table being locked fast to said gear wheel B bymeans of a bolt G, engaging eorrespondngsockets.in the respect-l iveparts. The .rotary motion of the apparatus is continued until the lowestturn ofi the rope -L about tube O has reached thelevvel. of the gears C,when Vthe latch G is thrown out of engagement with gear B and the pin? Zis inserted through `the openings in jaws and table A. The gears Eare:then throwni into engagement with gears B and C when the ltable A willremain stationaryand rotaryf motion will be imparted to drums C .and`through the rope thereabout totube O, the'` Wire rope L in this casehowever, rising on? the 4tube at each revolution of the same, as i Inthe operation of thef apparatus, the rope rises on tube O at each;revolution, the amount .of its diameter, lessy the distance the pipe hasbeen lforced into the earth, and in operating in ordinary soft materialthese two items will be about equal and as long as this conditionremains, the op-` eration `as last described `may be vcontinued.` Butshould the tube not enter Vthe earth suf` ciently fast, from theresistance offeredthere-' toor any cause, the rope ascends on ,the pipeand drums to near vthe top of the latter whenE the `table A will beagain loosened from` brackets F, gears E thrown out of engage. ment asshown in dotted lines in Fig. 1, said gears being eccentricallyjournaled in the. table vA in any Well known manner and bolt G droppedinto the socket in gearwheel B;

when the first described method will ybe resumed until theprope hastraveled down again z 'the necessary slack being given and taken up asthe rope travels up and down by means of hand wheel K. Slack should alsobe given to admit the passage of the couplings through the apparatus.

In order to provide against back rotation vof tube O,when the apparatusis stopped froml any cause, I prefer to provide the block J with a chockor wedge-shaped block A as seen in s Fig. 2, which can be placed betweenthe top of the block J and the rope and thus stop the passage of therope through the block in the well known manner.

In operating upon very hard substances,

there is a constant tendency for the rope L to slip and to prevent this,as Well as to remove undue strain therefrom, I provide a clamp as seenin Fig. 4, which consists of two halves or sections c, having bolts bheaded on one side thereof and passing through the ends thereof to theends of which bolts are coupled slotted cam levers d', c', as clearlyseen in said View. The sections c, have arms c', which, when the deviceis in place about the tube O, project laterally and engage with the'drums C', C', on each side of the apparatus so that when the sectionsare clamped fast to the tube or casing said tube will be rotatedpositively from table A, without recourse to rope L in driving.

I do not Wish to be understood as limiting myself to the preciseconstruction and arrangement of the various parts shown herein forcarrying my invention into practice, as it is evident that manyalterations maybe made therein without material departurefroln theprinciples thereof.
